2. Customers: This table contains data on all the customers who have used the company’s credit card processing services.

The data includes the customer ID, name, address, phone number, and email.

Conclusion

In conclusion, SQL is an essential tool in the world of financial analysis. It can be used to retrieve, store, organize, manipulate, and visualize data efficiently.

Furthermore, we utilized a sample database to demonstrate how SQL can be used in financial analysis. By analyzing the data contained in the database, financial analysts can make informed decisions about their financial situation.
